小黑麦是经小麦和黑麦人工杂交、染色体加倍而成的新物种，生物量大、抗逆性强、适应性广，兼具粮食和饲料的双重价值。为了科学评估小黑麦的适应性、高产特性和饲料利用价值，根据国家及行业相关标准，并结合多年小黑麦选育和生产经验，从物候期、形态特征、生育动态、抗逆性、病虫害、经济性状、品质性状等方面制定了小黑麦田间科学试验记载项目，同时规定了小黑麦产量及饲用品质指标的测定方法和计算公式。本标准适用于小黑麦品种(系)选育、引种试验、区域试验、生产试验、示范推广等田间性状调查鉴定及饲草品质分析各环节。

Triticale is a new species created through artificial hybridization of wheat and rye followed by chromosome doubling. It exhibits high biomass, strong stress resistance, and broad adaptability, making it an excellent dual-purpose crop for both grain and forage. To scientifically evaluate the adaptability, high yield characteristics, and feed utilization value of triticale, based on national and industry standards, combined with long-term experimental research and practical experience, scientific field trial recording items for triticale have been established. These items cover phenological stages, morphological characteristics, growth dynamics, stress resistance, pests and diseases, economic traits, quality traitsamong other aspects. Additionally, this study specifies methods and calculation formulas for determining and calculating triticale yield and feed quality indicators. This standard aims to provide scientific basis for the selection and breeding of triticale varieties (lines), introduction trials, regional trials, production trials, demonstration and promotion, as well as field trait surveys and feed quality analysis.
